Answer 2

Answer: D) 152 to 164

Explanation:

A+7B=112

it is clear that A = 14, then it becomes A>=B, but A is smallest angle) given

so, range of A is 0.0001 to 13.9999 ( I am taking upto 4 decimal places)

so, range of B becomes 14 to 16 ( after rounding off to 4 decimal places)

so, range of C becomes 152 to 164 ( after rounding off to 4 decimal places)
